Police are renewing their appeal for witnesses to the incident, which occurred on Call Lane at around 9pm on Saturday, to come forward.

Paramedics were called to the scene after receiving reports of a 43-year-old man outside a bar with serious injuries. He was taken by ambulance to Leeds General Infirmary and remained in a serious condition this morning.

As a result of initial enquiries, a 31-year-old local man was arrested on suspicion of assault and has now been bailed pending continuing police enquiries.

Acting Detective Chief Inspector Richard Holmes, of West Yorkshire Police’s Homicide and Major Enquiry Team, said: “We are keen to speak to anyone who has seen the circumstances of how this man has come to be injured. Any witnesses are urged to contact the Homicide and Major Enquiry Team via 101. Information can also be passed anonymously to independent charity Crimestoppers by calling 0800 555 111.”
